Genes affected
ZNF778 (HGNC:26479): (zinc finger protein 778) The protein encoded by this gene is a member of the krueppel C2H2-type zinc-finger protein family, and it contains one KRAB domain and eighteen C2H2-type zinc fingers. This gene is a candidate gene for autism and variable cognitive impairment in the 16q24.3 microdeletion syndrome. Alternatively spliced transcript variants have been found for this gene.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 21, 2023The c.116A>G (p.Q39R) alteration is located in exon 3 (coding exon 2) of the ZNF778 gene. This alteration results from a A to G substitution at nucleotide position 116, causing the glutamine (Q) at amino acid position 39 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
